Exploring the Causes of Low Immunization Status in School Going Children

Background: Although a definitive immunization program has been advocated for children in our country, the immunization coverage is far from satisfactory. There is paucity of survey studies related to immunization pattern. Objective: This study has been undertaken to explore the social and attitudinal factors with parents resulting into adverse immunization. Material and Methods: The study was school based cross-sectional study conducted in 50 schools of Indore district selected by random sampling from three groups. Information was collected from parents by providing pre-tested questionnaire. Result: Association of parent’s literacy and socioeconomic status with successful immunization could be established. Overall coverage rate with vaccines was poor in school going girls as compared to the boys; proving thereby that gender discrimination exists putting girls in disadvantageous position. Conclusion: It can be expected that the immunization status of school children will improve if identified risk factors such as parental education, socioeconomic status, awareness status are improved and attitudinal gender discrimination is curbed

The effect of genome length on ejection forces in bacteriophage lambda

A variety of viruses tightly pack their genetic material into protein capsids that are barely large enough to enclose the genome. In particular, in bacteriophages, forces as high as 60 pN are encountered during packaging and ejection, produced by DNA bending elasticity and self-interactions. The high forces are believed to be important for the ejection process, though the extent of their involvement is not yet clear. As a result, there is a need for quantitative models and experiments that reveal the nature of the forces relevant to DNA ejection. Here we report measurements of the ejection forces for two different mutants of bacteriophage lambda, lambda b221cI26 and lambda cI60, which differ in genome length by ~30%. As expected for a force-driven ejection mechanism, the osmotic pressure at which DNA release is completely inhibited varies with the genome length: we find inhibition pressures of 15 atm and 25 atm, respectively, values that are in agreement with our theoretical calculations

Snakebite: Admissions at a tertiary health care centre in Maharashtra, India

Objectives. To determine the outcome, seasonal variation, and death pattern of snakebite cases admitted at the tertiary health care centre in the last 10 years. Methods. This was a record-based retrospective descriptive study at the Dr Shankarrao Chavan Government Medical College and Hospital in Vazirabad, a tertiary health care centre in Maharashtra, India. Results. Out of 5 639 admitted snakebite cases, 65.24% were male. The 16 - 45-year age group accounted for 84.7% of cases; 46% were referred from other health centres, mostly from rural areas; 55.2% occurred during July to September, which coincided with the rainy season in this region; 94.6% of the snakebite patients survived; and 5.4% died. Case fatality rates were higher for females (8.78%) and for bites by neurotoxic snakes (8.91%). Conclusions. Snakebite is a common life-threatening emergency in the study area. Ready availability and appropriate use of antivenom, early referral when required and close monitoring of patients in the hospital will help to reduce mortality from snakebites

Broad-tailed force distributions and velocity ordering in a heterogeneous membrane model for collective cell migration

Correlated velocity patterns and associated large length-scale transmission of traction forces have been observed in collective live cell migration as a response to a "wound". We argue that a simple physical model of a force-driven heterogeneous elastic membrane sliding over a viscous substrate can qualitatively explain a few experimentally observed facts: (i) the growth of velocity ordering which spreads from the wound boundary to the interior, (ii) the exponential tails of the traction force distributions, and (iii) the swirling pattern of velocities in the interior of the tissue.Comment: 7 pages and 5 figure
